情况：将我的 Android 项目从带有 VisualOn 的旧 Ooyala SDK 更新到带有 Exoplyer 的最新 Ooyala SDK。通过 Amazon Fire Stick 播放视频。
问题：更新 SDK 后，项目不再工作。我们收到此错误消息：
- “E/AndroidRuntime：致命异常：主进程：com.ISN.firetv_isn，PID：19650 java.lang.NoClassDefFoundError：com.ooyala.android.player.exoplayer.ExoStreamPlayer”
查看 NoClassDefFoundError，我觉得代码缺少包的导入（但是，总的来说我不知道）。
.
请帮我定位问题。有什么解决办法？
